350 Strada Seat base.

[FatherB]

I'm looking for a 350 Strada seat base for a 1976 model. I'm pretty sure any base from an early Strada from 1974 to about 1978 would do. I only really need a good solid metal base as I want to extend the length and then re-cover it with new foam and vinyl cover to provide more room for a passenger. Therefore whether the cover and foam are present or in poor order doesn't matter as long as the base is in reasonably solid condition. Many thanks.
